Distribución espacial de elementos mayores y traza en suelos de la Estación Agropecuaria-UTPL y su relación con propiedades fisicoquímicas del suelo

Abstract

Abstract: The objective of this study is to analyze soil pH and texture and their relationship with the concentrations of major and trace elements. The research was conducted at the Agricultural Station-UTPL in the city of Loja. The methodology consisted of five phases: information gathering, fieldwork, laboratory analysis, data interpretation, and final report. Of the 84 soil samples, the most representative soil texture was loam with an acidic pH. Statistics and geostatistics using ordinary Kriging were used to process the data and interpolate the spatial distribution of the variables, which were then used to create threshold maps. Finally, the relationship between the geochemical variables and the textural map was analyzed, and a predictive map was created using the pH variables and geochemical elements through exhaustive CHAID classification tree analysis.
